ee1b6bc81b Create network_utils crate (#7761)
Anchor currently depends on `lighthouse_network` for a few types and utilities that live within. As we use our own libp2p behaviours, we actually do not use the core logic in that crate. This makes us transitively depend on a bunch of unneeded crates (even a whole separate libp2p if the versions mismatch!)


  Move things we require into it's own lightweight crate.

884f30094a use DEFAULT_TARGET_PEERS for target peers everywhere (#7916)
Was going to leave this as a comment on #7877 but when noticed it had already been merged.
we have `DEFAULT_TARGET_PEERS` which was set to 50 and only used on the `Default` impl for `peer_manager`'s `Config`, which then get's overridden by this `lighthouse_network::Config`s default
This PR unifies everything on `DEFAULT_TARGET_PEERS`

b43e0b446c Final changes for fusaka-devnet-2 (#7655)
Closes #7467.

This PR primarily addresses [the P2P changes](https://github.com/ethereum/EIPs/pull/9840) in [fusaka-devnet-2](https://fusaka-devnet-2.ethpandaops.io/). Specifically:

* [the new `nfd` parameter added to the `ENR`](https://github.com/ethereum/EIPs/pull/9840)
* [the modified `compute_fork_digest()` changes for every BPO fork](https://github.com/ethereum/EIPs/pull/9840)

90% of this PR was absolutely hacked together as fast as possible during the Berlinterop as fast as I could while running between Glamsterdam debates. Luckily, it seems to work. But I was unable to be as careful in avoiding bugs as I usually am. I've cleaned up the things *I remember* wanting to come back and have a closer look at. But still working on this.

Progress:
* [x] get it working on `fusaka-devnet-2`
* [ ] [*optional* disconnect from peers with incorrect `nfd` at the fork boundary](https://github.com/ethereum/consensus-specs/pull/4407) - Can be addressed in a future PR if necessary
* [x] first pass clean-up
* [x] fix up all the broken tests
* [x] final self-review
* [x] more thorough review from people more familiar with affected code

076f3f0984 Clarify network limits (#7175)
Resolves #6811


  Rename `GOSSIP_MAX_SIZE` to `MAX_PAYLOAD_SIZE` and remove `MAX_CHUNK_SIZE` in accordance with the spec.

The spec also "clarifies"  the message size limits at different levels. The rpc limits are equivalent to what we had before imo.
The gossip limits have additional checks.

I have gotten rid of the `is_bellatrix_enabled`  checks that used a lower limit (1mb) pre-merge. Since all networks we run start from the merge, I don't think this will break any setups.

f11884ccdb enforce non zero enr ports (#4776)
## Issue Addressed

Right now lighthouse accepts zero as enr ports. Since enr ports should be reachable, zero ports should be rejected here

## Proposed Changes

- update the config to use `NonZerou16` as an ENR port for all enr-related fields.
- the enr builder from config now sets the enr to the listening port only if the enr port is not already set (prev behaviour) and the listening port is not zero (new behaviour)
- reject zero listening ports when used with `enr-match`. 
- boot node now rejects listening port as zero, since those are advertised.
- generate-bootnode-enr also rejected zero listening ports for the same reason.
- update local network scripts

## Additional Info

Unrelated, but why do we overwrite `enr-x-port` values with listening ports if `enr-match` is present? we prob should only do this for enr values that are not already set.

dcd69dfc62 Move dependencies to workspace (#4650)
## Issue Addressed

Synchronize dependencies and edition on the workspace `Cargo.toml`

## Proposed Changes

with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.

## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.

should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.
closes https://github.com/sigp/lighthouse/issues/4651

e4ed317b76 Add Experimental QUIC support (#4577)
## Issue Addressed

#4402 

## Proposed Changes

This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP. 

This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.

NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

3397612160 Shift networking configuration (#4426)
## Issue Addressed
Addresses [#4401](https://github.com/sigp/lighthouse/issues/4401)

## Proposed Changes
Shift some constants into ```ChainSpec``` and remove the constant values from code space.

## Additional Info

I mostly used ```MainnetEthSpec::default_spec()``` for getting ```ChainSpec```. I wonder Did I make a mistake about that.

ff9b09d964 upgrade to libp2p 0.52 (#4431)
## Issue Addressed

Upgrade libp2p to v0.52

## Proposed Changes
- **Workflows**: remove installation of `protoc`
- **Book**: remove installation of `protoc`
- **`Dockerfile`s and `cross`**: remove custom base `Dockerfile` for cross since it's no longer needed. Remove `protoc` from remaining `Dockerfiles`s
- **Upgrade `discv5` to `v0.3.1`:** we have some cool stuff in there: no longer needs `protoc` and faster ip updates on cold start
- **Upgrade `prometheus` to `0.21.0`**, now it no longer needs encoding checks
- **things that look like refactors:** bunch of api types were renamed and need to be accessed in a different (clearer) way
- **Lighthouse network**
	- connection limits is now a behaviour
	- banned peers no longer exist on the swarm level, but at the behaviour level
	- `connection_event_buffer_size` now is handled per connection with a buffer size of 4
	- `mplex` is deprecated and was removed
	- rpc handler now logs the peer to which it belongs

## Additional Info

Tried to keep as much behaviour unchanged as possible. However, there is a great deal of improvements we can do _after_ this upgrade:
- Smart connection limits: Connection limits have been checked only based on numbers, we can now use information about the incoming peer to decide if we want it
- More powerful peer management: Dial attempts from other behaviours can be rejected early
- Incoming connections can be rejected early
- Banning can be returned exclusively to the peer management: We should not get connections to banned peers anymore making use of this
- TCP Nat updates: We might be able to take advantage of confirmed external addresses to check out tcp ports/ips

d399961e6e Add an option to disable inbound rate limiter (#4327)
## Issue Addressed

On deneb devnetv5, lighthouse keeps rate limiting peers which makes it harder to bootstrap new nodes as there are very few peers in the network. This PR adds an option to disable the inbound rate limiter for testnets.

Added an option to configure inbound rate limits as well.

714ed53839 Add a flag for storing invalid blocks (#4194)
## Issue Addressed

NA

## Proposed Changes

Adds a flag to store invalid blocks on disk for teh debugz. Only *some* invalid blocks are stored, those which:

- Were received via gossip (rather than RPC, for instance)
    - This keeps things simple to start with and should capture most blocks.
- Passed gossip verification
    - This reduces the ability for random people to fill up our disk. A proposer signature is required to write something to disk.

## Additional Info

It's possible that we'll store blocks that aren't necessarily invalid, but we had an internal error during verification. Those blocks seem like they might be useful sometimes.

7456e1e8fa Separate BN for block proposals (#4182)
It is a well-known fact that IP addresses for beacon nodes used by specific validators can be de-anonymized. There is an assumed risk that a malicious user may attempt to DOS validators when producing blocks to prevent chain growth/liveness.

Although there are a number of ideas put forward to address this, there a few simple approaches we can take to mitigate this risk.

Currently, a Lighthouse user is able to set a number of beacon-nodes that their validator client can connect to. If one beacon node is taken offline, it can fallback to another. Different beacon nodes can use VPNs or rotate IPs in order to mask their IPs.

This PR provides an additional setup option which further mitigates attacks of this kind.

This PR introduces a CLI flag --proposer-only to the beacon node. Setting this flag will configure the beacon node to run with minimal peers and crucially will not subscribe to subnets or sync committees. Therefore nodes of this kind should not be identified as nodes connected to validators of any kind.

It also introduces a CLI flag --proposer-nodes to the validator client. Users can then provide a number of beacon nodes (which may or may not run the --proposer-only flag) that the Validator client will use for block production and propagation only. If these nodes fail, the validator client will fallback to the default list of beacon nodes.

Users are then able to set up a number of beacon nodes dedicated to block proposals (which are unlikely to be identified as validator nodes) and point their validator clients to produce blocks on these nodes and attest on other beacon nodes. An attack attempting to prevent liveness on the eth2 network would then need to preemptively find and attack the proposer nodes which is significantly more difficult than the default setup.

This is a follow on from: #3328
